White rice typically has lower amounts of arsenic than brown rice. That's because the bran, or the outer layers of brown rice, and the germ are removed to make white rice, which decreases the amount of arsenic. Still, switching to white rice is probably not a good idea because white rice has very little nutritional value despite being lower ...Web
